Looks clear enough to me:

This extension excludes any re-opening of the Withdrawal Agreement. Any unilateral commitment, statement or other act by the United Kingdom should be compatible with the letter and the spirit of the Withdrawal Agreement, and must not hamper its implementation. Such an extension cannot be used to start negotiations on the future relationship.

Thanks btw.
